Ignition System Test
The Spark Kill diagnostic mode allows the technician to disable the ignition on individual cylinders. If the Spark Kill
diagnostic mode is selected with the engine running below 1000 RPM, the minimum throttle command will lock into
the position it was in when the test mode was entered. If the Spark System Test mode is selected with the engine
running above 1000 RPM, the throttle will continue to operate normally.
Disabling Ignition Ouputs
To disable the ignition system for an individual cylinder, use the mouse to highlight the “Spark Kill” button and select
the desired coil. The spark output can be re-enabled by using the mouse to highlight the “Spark Kill” button and
selecting “Normal”. If the engine is running below 1000 RPM, the spark output will stay disabled for 15 seconds and
then re-set. If the engine is running above 1000 RPM, the spark output will stay disabled for 5 seconds and then re-
set. This test mode has a timeout of 10 minutes. Record the rpm drop related to each spark output disabled.
The Spark outputs are arranged in the order which the engine fires, not by cylinder number.
